to the side bars by means of bolts-5 and 6. The lower ends of the brackets terminate in bearings 7 for a transverse shaft 8. This shaft is held in place by-pins at'opposite ends of the shaft or in any other suitable manner and the shaft rotates loosely Within the bearings 7. Mounted upon the shaft are a plurality of presser Wheels designated 9.

l There are as many of these presser wheels as may be desired, depending upon the length of the frame formed by the bars 2 and 3. Preferably each of the presser wheels is sixteen inches high with `a tread 3% Wide. Each wheel comprises a tread 10, a hub 11 and spokes. Of course, the particular form of the Wheel is not important. The hub 11 is wider than the tread 10, and preferably the hub 11 is 4 Wide. When these presser disks or wheels are placed along the shaft..

with their hubs abutting against each other, a space one-half vinch Wideis left between the treads of adjacent Wheels for a `purpose that will be later explained. Formed -upon the treadl of the Wheel are a plurality of lugs 12 shown as six in number onia' 16 wheel,

these lugs projecting beyond the surface of the wheel about 1%. Thesevlugsare approximately 251g wide and 4% longbat thel base. As illustrated in Fig. fthese lugs have slanting side faces a and end faces b slanting outwardly and toward they middle plane of the wheel and a straight sided portion or rib c forming the apex of the lug and of the same length as the outer portionl hub with a bore 2% in diameter and use a 2 shaft. The bore of each hub yis formed with divorging slots or channels `14,and 15'l meeting at the middle plane of thev hub and extending Aoutward to the ends of they hub.

The rear frame bar 2a of the forward gang is ex tended on each-side beyond -the series of disks or Wheels, and therear gangs are loosely linked, each at 'its middle as at 16 to this rear frame bar 2a. The end brackets 17 of the rear gangs are connected at 18 by a loose connection to the frame bar Qso 'thatl the rear gangs may move freely to conform to the surface of the ground. I have also shown a tongue 19 connected to the forward gang.

It is to be noted that the tread of each ,wheel or disk is Widerthan the base of the lugs 12 mounted thereon and that these lugs are spaced from each other. The purpose of this is as follows: The tread face 10 tends to compress the soil so as to force the particles of the surface soil into contiguity with each other and compaetit. Each lug, as the wheel moves over the ground, forms'a cup,

depression 'or pocket D in the ground and at the bottom of each main depression there is formed a.' straight sided, longitudinally exh `tending depression d. Th-e soll on each side and in front of and behind the -pocket' will be compressed. The soil at thesides of the main pocket D will also be compressed, by

f the beveled faces of the lugs.. The soil at the bottom of the pocket d will also becompressed but the soil at the sides of the small therefore loose as illustrated in the sectional View, Fig. 5. As a consequence rain will tend to gather in the cups, depressions or pockets D and the water can easily get through into the` ground through the side walls of the portion d, the ground not being packed at that point. Afcoiitinuously cor-I extension d of the main pocliet will not be .confipressed but will be cut through vand iiigzited roller would press the groundevenly overxits entire extent so that in anordinarily' heavy rain, the soil will start to wash away. `With my improved roller, the water Will not act to wash away 'the upper soil but will WILLIAM L.

To all whom t may concern.'

Be it known that I, WILLIAM f citizen of the United States, residing at Kearney, in the county of Buffalo alifd Sta-te of Nebraska, have invented certain .new and useful Improvements in Land Rollers, PackeI-s, and Pulverizers, of which the following is aspecification.

My invention'v relates to land rollers or packers, and particularly to a. roller. of this character having a plurality of rolling and packing p ulverizing disks.v

The primary objectof my invention is to4 provide a roller and packer of this general character so constructed that'it will press the ground evenly and firmly, thus preventing washing away of the surface of the soil, .and further so constructed that a. plurality of open cups will be formed in the surface of the soil designed to catch and`retain Wa-.

ter which may fall thereon.

A further object is to so form the roller l that thzeliikpper soil around the cup and at the bottom'fof the cup will be compressed while the soil of the lower side or Wall of the cup will be relatively loose so that water can easily pass into the ground an'rinch or so below the surface and be retained' thereinV from evaporation.

Afurther object in this connection'isvto provide a roller which is not only adapted to perform the function above referred to, but which'is also adapted for treating the soil for winter wheat, it being used early in from the hub.

thc spring to break the crust of the soil and Y perforate the ground so that it will receive the spring rains and hold the moisture through the dry period which usually fol'- lows.

ln general it. may be said. that my improved roller is especially intended to so" prepare soil that it will not only receivev the rain but `retain the moist-ure within the soil.

A further object of the invention is to provide an agricultural machine of this character comprising a plurality of disks, the disks being vloosely mounted upon .a transverse shaft in such manner asnotto require :the Aapplication 'of any lubricating oil to. the'shaft, and insueh manner ,that dust or' dirt which would-otherwise be liable to accumulate between the hub of the wheeland the shaft shall' be automatically ejected specification er Letters Patent formedin the soil.

Patented Augz, 1913.

A further object is to provide a machine .of this character including a plurality of pressing `mounted upon a shaft with means whereby., the shaft may rotate independently of the Vloose pulverizing disks themselves, thus do-V ing away with thenecessity of using oil as panying drawings wherein:

Fig. 4t is a' side elevation of one of the rollers and showing the .peculiarform of the lugs thereon.
